General topics » Body Screws...shouldered versus non-shouldered question.

In doing work this winter, I ran into an issue. I had a body screw that would not fully seat because the hole was not sized to fit a shouldered screw...which is what was there. I figured BMW made a mistake in where they put screws last time they worked on the bike. I got down to removing the trim to the gas cap and found other non-shouldered screws, but there seemed to be no rhyme or reason to why they were there as a shouldered screw would work fine. Anyone know where the non-shouldered screws are intended to be used (I only can see two specific body trim panels that uses them)?

I used all shouldered screws on the painted bodywork. They are there to place the bodywork in precisely the right spot without damaging the paint or deforming the plastic.

When I installed my CF fender, I had to place 7x2 o-rings on the shouldered screws to make up the difference in bodywork thickness.

True, but I'm trying to ID where the non-shouldered ones get used. I only know of two spots and I think I found a total of 6 when I did my mods.

I have the XR, the RS and a GS, and I can't recall seeing a non-shouldered bolt anywhere, on any of them.

Try the fiches on this site, shows where the shouldered (item 6) & non-shouldered bolts (item 4) should be eg on the textured black side panels but there are other places too IIRC.

I had most of the bodywork off mine last month while I was installing the Cyclops turn signals and encountered a similar issue.

As I recall, the colored bodywork needs the screws with the shoulders. If you look, you'll see two sizes of holes and the colored bodywork always had the larger size. On the other hand, the matte black sections often had smaller holes, but not always. I realized this after I had take some screws out and mixed them up. Afterwards, I was diligent in keeping track and I would immediately thread the screw back into the hole it came out of.

Anyway, take a good look and you should see cases where the shouldered ones simply don't fit through the hole in the bodywork Use the non shouldered ones there.
